Abstract:

In this study, the aim is to determine the water quality according to the diathomic flora and physical and chemical parameters of Ulupınar Tea and Olimpos Skin, which are of great importance in the tourism. In total, 6 stations, including 4 on Ulupınar Tea and 2 on Olympos Deres, have been determined by seasonal landwork. Biological oxygen need (BOI5), ammonium nitrogen (NH4-N), nitrate nitrate (NO2-N), nitrate nitrate (NO3-N), chloride (Cl-), temperature ( ̊C), soluble oxygen (mg/l), pH and electrical conductivity (μS/cm) have been measured and water quality classes have been determined in accordance with the Surface Water Quality Regulation (YSKY). According to the epilithic diathoms, water quality classes were evaluated while using GDI, TDI, SI, TI, TDI and DI-CH. Sørensen similarity and Margalef diversity analyses have been conducted to reveal the differences or similarities of specified taxons from the point of view of stations. According to YSKY, OD1 is usually II. It has been found in quality class, while other stations are usually in quality class I. In this study, 64 taxons of 33 genres of epithelial diathomas were detected. The breed that has the most species has been Nitzschia with 8 species. The most dominant taxon in the study was Achnanthidium minutissimum (Kützing) Czarnecki. According to epilithic diathoms, UÇ1, UÇ2 and OD2 are usually I-II. In the quality class, UÇ3 and UÇ4 are usually II. In quality class, OD1 is determined in quality class I.
